GRATE.

SPECIFICATION forming part of Letsel-sment No. 698,630, dated April 29,"1902.

Application led March 5, 1901.`

To all whom. t may concern:

Be it known that I, EDWIN R. CAHOONE, a citizen of the United States,residing at Newark, in the county of Essex andtate ofV New Jersey, haveinvented new and useful Improvements in Grates, of which the followingis a specification.

This invention relates to improvements in swinging vertical gratos forstoves.

The object of the invention is to provide a swinging grate of suchconfiguration that the capacity of the fire-pot may be quickly andreadily increased or decreased, according to the will of theoperator-that is to say, if the grate be locked to position itsconvexity toward the front a large lire can be made in the iire-pot. Onthe other hand, if the concave portion of the grate be positioned towardthe front then the coal capacity of the fire-pot will be greatlydiminished.

A further object of my invention is to provide a reversible verticalgrate which will enable the operator to suitably support and house abroiler and drip-pan, thereby securing the benefit of the heat fortoasting and broiling purposes, at the same time preserve allthe dripsor juicesas they drop.

Many other objects will become apparent in the description to follow,and particularly pointed out in the claims. I

In the drawings forming a part of this speciiication, Figurel is avertical section of a portion of a stove, showing the application of myinvention, the grate being positioned to enlarge the fire-pot. Fig. 2 isa similar view showing the grate turned to diminish the size of there-pot. Fig. 3 is a perspective view of the grate and itssupporting-frame. Fig. 4 is a perspective view showing a broiler incasedbetween the frontdoor and the grate, the latter being in the positionshown in Fig. 2. Fig. 5 is a detail view of the door-hinge. Fig. 6 is adetail View ofa shield used to prevent the smoking of the mica windowsin the air trunks or tubes.

The same numerals refer to like parts in al1 the figures. A l

1 indicates a stove having a front opening 2 adjacent the re-pot 3, saidopening being covered by a door 4, supported bya suitable frame 5. Thedoor is loosely hinged at its lower corner, as at 6, the hingeconnection consisting of serial No. 49,821. or@ man.)

a pivot 7, extending from the rear of the door, anda locking-lug 8,projecting from the pivot. The frame 5 has a perforation 9 and a notch10, communicating with said perforation, through which the locking-lugSpasses when the pivot-pin engages the perforation 9. To fit the door, itis tilted on one end, as indicated by dotted lines in Fig. 4, to permitthe locking-lug 8 to pass through the notch 10. Then the door is swungdown on its pivot 7, the latter being retained in place by thelocking-lug 8 catching against the wall surrounding the perforation 9.This hinge connection is so constructed as to permit of considerablelost motion, the purpose of which will be hereinafter referred to. Thedoor is preferably provided with trunks or tubes 26 to permit a freesupply of air topass to the fuel. However, as the details of thesedevices form no part of my present invention it is not deemed necessaryto further describe them.

Secured to or formed with the door-frame 5 lis a grate-supportin g frame11, composed of end `heads or flanges 13 13 and connectingbars 14 14.The heads 13 have bearings for trunnions 15, which are formed on projec--tions on the ends of the grate 16, these trun- `nions being locked inposition in any Wellknown manner-for instance, that indicated at 17.

. The grate 16 is composed of a series of parallel hooked shape bars 18,spaced apart and connected at their ends, as indicated at 19. Incross-section each `bar is somewhat beveled on both sides to offer aslittle resistance as possible to the air as it passes to the fuel.

` On the upper and lower edges of the grate is a perforation 20, withone of which a lockingpin 21, preferably in the top of the frame 5,engages when it is desired to hold the grate in a given position.

Betweenthe frame 5 and the top of the grate is a suitable space formingafree passage between 4the space behind the door and the re-pot, thepurpose of which is to permit the gases behind the door. to be drawninto the fire-pot when the door is opened.

When the convex side of the grate is turned toward the front, it bringsthe parallel bars in close proximity with the mica windows 25 in thetrunks 26, and not infrequently this relationship causes theaccumulation of soot IOO ` shield is used are almost closed, permittingre of medium size to be made.

ot' a sufficient current of air, but not open enough to cause the smokeand soot to collect on the windows. Y

The lower portion of the frame 5 and the bottom grate 31 are soconstructed and arranged as to form a pocket 32 to accommodate adrip-pan`33, which is approximately of V shape in cross-section and iscomposed of the inclined sides 34, ends 35, and handle 36. As disclosedin Fig.`2, the pan may be supported by lugs 37, resting on the frontgrate, and the handle, resting on the frame 5. A In conjunction with thefront grate and the drip-pan I use a broiler 38 of any wellknown type.The broiler is supported by rests 39 on the lower part of the frame 5and a hook40, seated in a slot 41, formed in a lug 42 in the frame 5.The handle of the broiler projects up through a notch in the door and isalways in convenient reach of the operator.

The operation of my invention is substantially as follows: In extremelycold climates, where a large fire-pot is a thing of necessity, thefrontgrate 16 is swung on its trunnions to the position shown in Fig. 1,when the lockpin engages the perforations 2O and the grate is fixed. Byreason of the `position of the trunnions and the curved hooked end ofthe grate the vertical portions of the bars are some distance from thefront extremities of the bottom grate. However, the latter are in linewith and practically touch the extreme end of the hooked portion of saidbars. The two grates form an unbroken front and bottom grate-section. Asbefore stated, when the front grate is turned in this position theshield is employed, this by reason of the close proximity of thegrate-bars to the mica windows. Should, however, it be desired todiminish the size of the fire-pot, the pin 21 is removed, the grateturned as shown in Fig. 2,- and the pin 21 inserted in theoppositeperforation in the grate. With the parts in this position the shield 27is removed and the grate-bars are nearer the center of the iire-pot, thestraight portion of said bars being now at the bottom and the lower endsabutting against the front of .the lower grate, while the hooked ends ofsaid grate are at the top. This position, like the one previouslydescribed, presents practically an unbroken front and bottomgratesection, and yet the width of the tire-pot has been materiallydecreased, which enables a With the grate-bars turned inwardly quite aconsiderable space is formed between the door 41 and the grate, in whichspace the broiler is supported. To apply the broiler, the door is thrownup and around on its pivot, the drippan is dropped in its seat, the hookon the broiler is slipped in its seat, and the lower end caught by therests. With the parts in this position it stands to reason that the meatbeing broiled receives every advantage from the surrounding temperature.Not only is the broiling action going on, but the juice incident to suchaction is caught and readily preserved, the drip-pan being so located asto be almost out ot' reach of the excessive heat,cooling somewhat thetemperature of the juice. Should it be preferred to incase the broiler,the door 4 can be almost closed, so much so that to all intent andpurposes the broiler will be out of sight. The door does not cover theentire opening when Yso used and is made to adapt itself to thisposition by reason of the lost motion between the hingejoint. Thisallows a sufficient quantity of air to pass in around the door to thebroiler,which adds considerably to the broiling action.

I-Iaving thus described myinvention, what I claim is-'- 1. A stovecomprising a casing having an opening in one of its walls, a tire-potadjacent said opening, and a grate extending from the top to the bottomof and pivotally supported horizontally in said opening in the casing,-adapted to be reversed to increase the size of the tire-pot in oneposition and decrease said tire-pot when turned over in the oppositeposition, substantially as described.
